Nice article, but are we taking an agent's word for something? 
Great point but I can't think of a reason or what kind of positioning he was going for here. His cleint already signed a contract so he doesnt need to endear him to the fanbase or the team. So now for him to make money, it seems like he would have to get Rondo sponsorship deals. Releasing to the media that Rondo turns down almost everything would give a bad impression to potential sponsorship opportunties. Do you disagree?
No, he's trying to create the impression that Rondo is a good guy and player. He's also subtly drawing attention to the fact that Rondo doesn't have a ton of endorsement deals, and that companies should take a look at him.
The statement comes right before he's named to his first all-star game to boot. Rondo's agent is doing his job, trying to raise Rondo's profile and get him some more dollars.
What he says very well could be true, but agent's words can't be taken at face value.
